Auto merge of #14153 - vvuk:win32-dwrite, r=glennw

Add support for DirectWrite font rendering on Windows

<!-- Please describe your changes on the following line: -->
This PR adds support for DirectWrite text rendering using a thin wrapper for dwrite, as well as similar functionality added to WebRender.  In doing so it removes the FreeType dep from the Windows build.

There is still work to be done here, but this is a good starting point for future cleanup and fixes.
